A bright sunny afternoon and the mink was out fishing. That blue colour of the water is actually the reflection of the clear blue sky in the still pools.
And no, a mink can't walk on water (Photo #3 & Photo #4). It's the fallen marsh reeds creating a bed under the water that the mink is prowling along. It actually swam under the reed bed looking for fish with some success but scampered quickly away with its small catch before you could say "mustelid".
